Description

Technical Field

[0001] This utility model relates to the technical field of automotive parts processing equipment, specifically to an automotive parts processing positioning device. Background Technology

[0002] As a component of automobiles, the exhaust pipe needs to be coated during the production process. Anti-corrosion coatings can ensure the corrosion resistance of the exhaust pipe during use and extend its service life.

[0003] During the painting process of automobile exhaust pipes, a clamping device is usually required to hold and position them. However, most existing clamping mechanisms clamp the outer wall of the exhaust pipe. During the painting process, the clamped area cannot be completely painted, which reduces the painting quality and efficiency of automobile exhaust pipes. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a positioning device for automotive parts processing.

Each clamping assembly includes a support frame, a slide groove, and a clamping seat. The lower end of the support frame is provided with a slider that passes through the slide groove. The lower end of the processing table is provided with a first motor. The output end of the first motor is provided with a rotating shaft. Two screws that pass through the slider are symmetrically arranged on the rotating shaft. The two screws have a reverse thread structure. The clamping seat passes through the support frame and is rotatably connected to the support frame. One end of the clamping seat is provided with a tapered clamping block, and the other end of the clamping seat is provided with a driven gear.

[0008] A side block is fixedly installed on one side of the support frame, a rotating block is rotatably installed on the side block, a support rod is fixedly installed on the rotating block, and a drive gear that meshes with the driven gear is provided at the outer end of the support rod. A fixed box is provided at the upper end of the processing table, a second motor is provided on one side of the fixed box, a fixed rod is rotatably installed on the fixed box, the support rod is inserted into the fixed rod and can extend and retract inside the fixed rod, a worm gear located inside the fixed box is provided in the middle part of the fixed rod, and a worm gear that meshes with the worm gear is provided at the output end of the second motor.

[0009] Furthermore, an improvement of this utility model is that the support frame and the second motor are servo motors.

[0010] To improve the stability of the support frame during use, the present invention includes an improvement in that the top of the slider is provided with a limiting plate that contacts the upper end of the processing table.

[0011] To improve the limiting effect of the conical clamping block on the exhaust pipe, the present invention is improved by providing anti-slip texture on the outer wall of the conical clamping block.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 The present invention relates to an automotive parts processing and positioning device, comprising a processing table 1, on which two clamping assemblies are symmetrically arranged. Each clamping assembly includes a support frame 2, a slide groove 3, and a clamping seat 8. The lower end of the support frame 2 is provided with a slider 4 that passes through the slide groove 3. The lower end of the processing table 1 is provided with a first motor 5. The output end of the first motor 5 is provided with a rotating shaft 6. Two screws 7 that pass through the slider 4 are symmetrically arranged on the rotating shaft 6. The two screws 7 have a reverse thread structure. The clamping seat 8 passes through the support frame 2 and is rotatably connected to the support frame 2. One end of the clamping seat 8 is provided with a conical clamping block 9, and the other end of the clamping seat 8 is provided with a driven gear 10.

[0026] A side block 11 is fixedly installed on one side of the support frame 2. A rotating block 12 is rotatably installed on the side block 11. A support rod 13 is fixedly installed on the rotating block 12. A drive gear 14 that meshes with the driven gear 10 is provided at the outer end of the support rod 13. A fixed box 16 is provided at the upper end of the processing table 1. A second motor 17 is provided on one side of the fixed box 16. A fixed rod 15 is rotatably installed on the fixed box 16. The support rod 13 is inserted into the fixed rod 15 and can extend and retract inside the fixed rod 15. A worm gear 18 located inside the fixed box 16 is provided in the middle part of the fixed rod 15. A worm 19 that meshes with the worm gear 18 is provided at the output end of the second motor 17.

[0027] The device is based on the processing table 1. It uses two symmetrically arranged clamping components to position and clamp the car exhaust pipe. When the first motor 5 is started, the rotating shaft 6 at its output end drives the two screws 7 to rotate. Since the two screws 7 have a reverse thread structure and pass through the slider 4, the rotation of the screws 7 will cause the two sliders 4 to move relative to or towards each other along the axial direction of the screws 7. This will drive the support frame 2, the clamping seat 8 and the conical clamping block 9 to move, so that the conical clamping block 9 can approach and be inserted into both ends of the car exhaust pipe. When the conical clamping block 9 is inserted into both ends of the car exhaust pipe, it can achieve stable clamping and limiting of the exhaust pipe by utilizing its conical structure and the anti-slip texture on the outer wall.

[0028] Rotation control principle: When it is necessary to spray the clamped car exhaust pipe, the second motor 17 starts, and the worm 19 at its output end meshes with the worm wheel 18 in the middle part of the fixed rod 15, driving the fixed rod 15 to rotate. Since the support rod 13 is inserted into the fixed rod 15 and can extend and retract, the rotation of the fixed rod 15 will drive the rotating block 12 to rotate through the support rod 13. The drive gear 14 on the rotating block 12 meshes with the driven gear 10 at the other end of the clamping seat 8, thereby transmitting power to the clamping seat 8, so that the clamping seat 8 drives the conical clamping block 9 and the car exhaust pipe to rotate, so that the outer wall of the exhaust pipe can be evenly sprayed through the specified spraying equipment. By controlling the rotation angle and speed of the second motor 17, the rotation of the car exhaust pipe can be precisely controlled.

[0029] When the support frame 2 moves, the support rod 13 will extend and retract within the fixed rod 15. Since the support rod 13 has protrusions on both sides, the support rod 13 will not slip when the fixed rod 15 rotates.

[0030] In this embodiment, the support frame 2 and the second motor 17 are servo motors.

[0031] When it is necessary to position exhaust pipes of different specifications, the conical clamping block 9 can be replaced. The center of the conical clamping block 9 is provided with a bolt 20 that is inserted into the clamping seat 8.

[0032] In this embodiment, the cross-section of the groove 3 is rectangular.

[0033] Operating steps:

[0034] 1) Equipment preparation: Place the automotive parts processing and positioning device in a suitable working area, ensure that the equipment is installed securely, connect the power supply, and check whether the first motor 5, the second motor 17 and other components are working properly.

[0035] 2) Positioning preparation: Start the first motor 5 to make the screw 7 rotate, which drives the support frame 2 and the clamping seat 8 to move through the slider 4, moving the conical clamping block 9 to the appropriate initial position, which is convenient for subsequent insertion of the car exhaust pipe.

[0036] 3) Exhaust pipe placement and clamping: The car exhaust pipe is manually placed in a suitable position on the processing table 1, ensuring that both ends of the exhaust pipe are aligned with the conical clamping block 9. The first motor 5 is restarted to insert the conical clamping block 9 into both ends of the car exhaust pipe, thereby clamping and fixing the exhaust pipe.

[0037] 4) Processing Operation: Based on specific processing requirements (such as spraying), start the corresponding processing equipment. At the same time, start the second motor 17, which, through the gear and worm gear 18 and worm 19 transmission mechanism, causes the car exhaust pipe to rotate, so as to uniformly process all parts of the exhaust pipe.

[0038] 5) Processing Completed: After processing is complete, first stop the processing equipment, then turn off the second motor 17 to stop the car exhaust pipe from rotating. Finally, turn off the first motor 5 to allow the conical clamping block 9 to retract from both ends of the car exhaust pipe, and manually remove the processed car exhaust pipe.

[0039] Unlike traditional external wall clamping methods, this device uses conical clamping blocks 9 inserted into both ends of the car exhaust pipe for clamping, avoiding obstruction of the spraying at the clamping point, allowing the car exhaust pipe to be completely sprayed, and effectively improving the spraying quality.

[0040] Because the exhaust pipe can rotate flexibly on the device, there is no need to frequently adjust the position of the exhaust pipe during the spraying process, which reduces auxiliary operation time and improves spraying efficiency.

[0041] In this embodiment, the top of the slider 4 is provided with a limiting plate that contacts the upper end of the processing table 1, which can improve the stability of the support frame 2 during use.

[0042] In this embodiment, the outer wall of the conical clamping block 9 is provided with anti-slip texture, which can improve the limiting effect of the conical clamping block 9 on the exhaust pipe.

[0043] The limiting plate at the top of the slider 4 can contact the upper end of the processing table 1, increasing the stability of the support frame 2 during use and preventing it from shaking or shifting during operation. Meanwhile, the slide 3 uses a rectangular cross-section, which improves the stability of the slider 4 during movement and ensures the reliability of the entire device.

[0044] Good limiting effect: The outer wall of the conical clamping block 9 is provided with anti-slip texture, which increases the friction with the inner wall of the car exhaust pipe, and can more firmly limit the exhaust pipe, preventing the exhaust pipe from loosening or shifting during the processing.

[0045] Easy assembly and maintenance: The center of the conical clamping block 9 is provided with a bolt 20 that is inserted into the clamping seat 8, which makes the conical clamping block 9 easy to install and disassemble, and easy to replace when worn or damaged, thus reducing the maintenance cost of the equipment.

[0046] Precise control: The support frame 2 and the second motor 17 adopt servo motors, which can achieve precise control of the device, meet the precise requirements of different processing technology for the rotation angle and speed of the exhaust pipe, and improve the accuracy and quality of processing.
